Grout that was not sealed in shower


A friend recently contacted me and asked me for help. He told me that he was watching a home improvement show where they mentioned the importance of sealing shower tile grout. He said that when he and his brother did their tiling a year ago, they never sealed it - he said he never even heard of doing it before. I told him I would help him seal it now if it's the right thing to do. I have a few questions.

1. Is it worth doing after a year has passed?

2. there are some spots on it where it looks like either the grout has worn down, was scrubbed too hard, or was never properly done in the first place. These areas are relatively few, but there is a noticeable dip in the grout there.

He still has some of the grout they used originally. Is it possible to just mix up some grout and go over the old grout to fill in the areas where it is slightly down? Will it bond? Or would we need to remove all the old grout and regrout the entire shower?

Thanks.

I would use a small hand grout removal tool and remove about 1/4 to 1/8 of and inch of grout and then re-grout. Make sure it is fully cured prior to sealing.

1/4" is just about all of it... Why not just remove it all if I'm going to go that far? I think if it's impossible to "top off" the grout so to speak, I'm just going to leave it. It's really not that bad. Not worth removing all the grout!

I definitely would not do the whole thing over. I would sooner rip it down and put up new tiles before I did that! I just meant the "spots on it where it looks like either the grout has worn down, was scrubbed too hard, or was never properly done in the first place" should be removed and re grouted.

Grout sealers only real purpose is to make the grout easier to keep clean--

Most modern grouts are a modified mix (contains a latex additive) and are quite good at resisting stains without a sealer----

If you wish to seal it now--go ahead---no harm was done--

Thanks! What is your opinion on adding to the low spots?
